Something inside the heart: a myxoid liposarcoma with cardiac involvement.

A 70-year-old man presented with dry cough, dyspnea and fatigue. Physical examination revealed only a grade 3 heart murmur. The chest X-ray showed bilateral nodular opacities. A CT scan revealed several nodular masses in both lungs, pleura and abdomen, as well as a similar lesion inside the left ventricle. Echocardiography revealed not only the pedunculated nature of this lesion, but also infiltration of the ventricular wall. Biopsy showed it to be a myxoid liposarcoma. Since the disease was already widespread, and given the characteristics of the intraventricular mass, only palliative measures were prescribed.
